About watt-hours and electronvolts
The Conversion Formula
To convert watt-hours to electronvolts, multiply the value by the conversion factor: 1 Wh = 2.2469e+22 eV. For a worked example, suppose you need to convert 25 Wh to electronvolts: 25 × 2.2469e+22 = 5.6174e+23 eV. To convert in the opposite direction, divide by 2.2469e+22, or equivalently multiply by 4.4505e-23.
About watt-hours
The watt-hour (Wh) is a smaller version of the kilowatt-hour. It is the standard for rating the capacity of batteries in laptops, smartphones, and power banks. Airlines often limit spare batteries to 100Wh for safety. watt-hours are commonly used in Laptop batteries, Power banks, Smartphone specs, and Drone batteries, Portable speakers.
A typical phone battery holds 10-15 Wh.
About electronvolts
The electronvolt (eV) is the tiny unit of energy used in particle physics. It is the energy gained by an electron accelerating through 1 volt. It is essential for describing photon energy, chemical bonds, and nuclear reactions. electronvolts are commonly used in Particle physics, Semiconductors, Nuclear energy, and Chemistry bonds, Microscopy.
A photon of visible light has an energy of about 2-3 eV.
When Would You Convert watt-hours to electronvolts?
Converting between watt-hours and electronvolts is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 Wh = 2.2469e+22 eV) memorized or bookmarked can save time in professional and everyday contexts alike.
